I have not heard anything about what safeguards Cozy has put in place in case they or their third party partner suddenly have stability issues.I'm not saying the sky is falling and we shouldn't trust anyone.

I found a property under contract that has R4 zoning with some sensitive area.

Resolving the situation outside of court will save you the most money but it will take effort, sensitivity, and persistence to make it happen.

As a safeguard, you could keep your parents on as minority owner ship, ex: 70% you 30% them. 

Yes, you need to be price sensitive to a certain extent, but you also "get what you pay for".

Ask for sensitivity analysis report - good syndicators should share w/you what happens if occupancy goes to "x" in a downturn, what's my return look like?  

You should only work with someone that you know and trust with your sensitive information.

Specifically, in Castro Valley.My parents live with me as well as my sister and I have been realizing that working a full time job will not get me enough money for retirement as I take care of my parents and try to safeguard the future of my kids.

It's highly sensitive to demographics and a declining business in some areas of the country.

This especially now as the topic of Airbnb is somewhat sensitive in Hawaii.Hope this helps, brahdah!
